Harold is death, Maude life, and they manage to make the two seem so similar that life's hardly worth the extra bother. The visual style makes everyone look fresh from the Wax Museum, and all the movie lacks is a lot of day-old gardenias and lilies and roses in the lobby, filling the place with a cloying sweet smell.

As performers, they both are so aggressive, so creepy and off‐putting, that Harold and Maude are obviously made for each other, a point the movie itself refuses to recognize with a twist ending that betrays, I think, its life‐affirming pre tensions.
